PHP 8.5: SplObjectStorage::attach() is deprecated

[Soean]

Describe the bug

When I run wpstarter with PHP 8.5, I see a deprecation:

Method SplObjectStorage::attach() is deprecated since 8.5, use method SplObjectStorage::offsetSet() instead, in wecodemore/wpstarter/src/Step/Steps.php line 109.

https://github.com/wecodemore/wpstarter/blob/version-3/src/Step/Steps.php#L109

SplObjectStorage::offsetSet() is an alias of SplObjectStorage::attach().
